T869,020 PROCESS FOR MAKING CHENILLE-TYPE YARN Charles W. Kim, Wilmington, Del., assignor to Hercules Incorporated, Wilmington, Del., a corporation of Delaware Filed May 2, 1969, Ser. No. 821,414 Int. Cl. D02g 3/42 US. Cl. 57-156 1 Sheet Drawing. 3 Pages Specification Novel decorative yarns are prepared by laying up a nonwoven web comprising a series of parallel warp yarns bonded to filling yarns and thereafter separating the web into strips along lines substantially parallel to the warp yarns and twisting the resultant product to form chenilletype yarns. The filling yarns can be either continuous filament or random laid staple fibers. Separation of the web into strips is accomplished by slitting in the case of continuous filament filling yarns or by simple mechanical pulling apart in the case where staple fibers are used in the filling.
